Unless you have no interest in getting a traditional publishing deal. My goal is to make a full-time living as an author, and, in broad strokes, I’m convinced self-publishing is the best route for that. So I don’t have the convenience of a literary establishment to give legitimacy to my work.

So maybe it’s about sales numbers. But what’s enough? 100 sales per month? 1,000? 10,000? It feels totally arbitrary. There’s always going to be someone selling more than you, and as soon as you’ve sold any books at all you’re in a pretty high percentile among aspiring authors. And there’s such a smooth gradation in between that I don’t think I’d be satisfied by reaching any particular number; it would just be time to bump the number up and start again.

Same goes for income. I do have a specific target income in mind that would allow me to quit my day job and write full time, but even there, how long do I need to sustain that income before it’s justified to make the leap? And who says that means I’ve made it? If I give in and write crappy 30,000-word self-help books with SEO’d titles that will sell like hotcakes and get me there faster have I really won at writing?

Is it enough for my family to barely scrape by on my writing income, or do we have to be marginally comfortable and secure before I’m really successful? Or do I need to be able to buy nice things or rent an office or something? Past a certain point, income is just another number. No, my financial goal just marks when I get to go full-time, not whether I’m succeeding as a writer.

In the end, I have settled on two measures of success. To measure my success as a writer, I always turn back to this:

1. Am I crafting worthwhile stories and ideas that only I can put into the world?
